Intel® Streaming SIMD Extensions 2 (Intel® SSE2) intrinsics for integer conversion operations are listed in this topic. The prototypes for Intel® SSE2 intrinsics are in the
To use these intrinsics, include the
immintrin.hfile as follows:
The results of each intrinsic operation are placed in registers. The information about what is placed in each register appears in the tables below, in the detailed explanation of each intrinsic.
R3represent the registers in which results are placed.
Intrinsics marked with * are implemented only on Intel® 64 architecture. The rest of the intrinsics are implemented on both IA-32 and Intel® 64 architectures.
